Wow! I just installed CS2 and it's awesome. I love how you can click in the screen to go to the Blending Options etc. Anyhow, not a big deal but still handy. I haven't really played around with the other features, I'm sure there are other improvements. Anyhow, Adobe also offers a rather large database of stock photos for use. The images are free at the smaller resolotions, IE used for web design. It's pretty awesome

Comp images are free, nonwatermarked, low-resolution versions of stock photos that you can download to use in mock-ups or other preliminary work. You can use comps to capture a feeling, idea, or concept before choosing the final image for a project. Comps are not licensed for production, but you can use them in mock-ups or other preliminary work. Because comps are low-resolution images, they’re not suitable for printing or publishing. After an evaluation period, you can purchase a high-resolution version of the image to continue working with the photo.
